Double-pin nail assembly

Abstract

The present invention relates to a nail assembly having one or more double-pin nails. Each nail includes a nail body and two nail pins extending from the nail body. Each nail pin has a tail end having at least one inclined face formed as a nail edge, where the inclined face is provided with at least one of a concave structure and a convex structure. The concave structure includes one or more grooves, and the convex structure includes one or more tenons. The assembly of double-pin nails having nail pin inclined faces provided with at least one of the concave and convex structures enables, after entering an object, the two nail pins of a double-pin nail are staggered to interlock with each other, thereby effectively connecting the object firmly with a strong anti-pull capability, and having desirable economic and technical benefits.

What is claimed is: 
     
       1. A nail assembly, comprising:
 one or more double-pin nails, wherein each double-pin nail comprises a nail body and two nail pins extending from the nail body, each nail pin having a tail end having a single inclined face formed as a nail edge, the single inclined face being provided with at least one of a concave structure and a convex structure, wherein the nail body and the two nail pins of each double-pin nail define a plane having a front direction and an opposite, rear direction that are perpendicular to the plane, and wherein the single inclined face at the tail end of one nail pin of each double-pin nail faces one of the front and rear directions, and the single inclined face at the tail end of the other nail pin of each double-pin nail faces one of the front and rear directions. 
 
     
     
       2. The nail assembly according to  claim 1 , wherein the concave structure comprises one or more grooves and the convex structure comprises one or more tenons. 
     
     
       3. The nail assembly according to  claim 2 , wherein the one or more grooves and/or the one or more tenons are determined according to a desired design. 
     
     
       4. The nail assembly according to  claim 1 , wherein the two inclined faces at the tail ends of each double-pin nail are symmetrical about the plane. 
     
     
       5. The nail assembly according to  claim 1 , wherein adjacent double-pin nails are connected to each other by using an adhesive or by soldering. 
     
     
       6. The nail assembly according to  claim 1 , wherein adjacent double-pin nails are connected to each other without using a tape or a strip. 
     
     
       7. A nail assembly, comprising:
 one or more double-pin nails, wherein each double-pin nail comprises a nail body and two nail pins extending from the nail body, each nail pin having a tail end having a single inclined face formed as a nail edge, the single inclined face being provided with at least one of a concave structure and a convex structure, wherein the nail body and the two nail pins of each double-pin nail define a plane having a front direction and an opposite, rear direction that are perpendicular to the plane, and wherein the single inclined face at the tail end of the left-hand side nail pin of each double-pin nail faces a left-hand direction, and the single inclined face at the tail end of the right-hand side nail pin of each double-pin nail faces a right-hand direction opposite to the left-hand direction, wherein the left-hand and right-hand directions are along the plane and perpendicular to a central axis of each double-pin nail. 
 
     
     
       8. The nail assembly according to  claim 7 , wherein the concave structure comprises one or more grooves and the convex structure comprises one or more tenons. 
     
     
       9. The nail assembly according to  claim 8 , wherein the one or more grooves and/or the one or more tenons are determined according to a desired design. 
     
     
       10. The nail assembly according to  claim 7 , wherein the two inclined faces at the tail ends of each double-pin nail are symmetric about the central axis of the double-pin nail. 
     
     
       11. The nail assembly according to  claim 7 , wherein adjacent double-pin nails are connected to each other by using an adhesive or by soldering. 
     
     
       12. The nail assembly according to  claim 7 , wherein adjacent double-pin nails are connected to each other without using a tape or a strip.
